METAL SHINGLE.

Application led December 4, 1912, Serial No. 734,956.

To all whom t may concer/n:

' Be it known that I, HARRY C. HAMES, a citizen of the United States, residing at London, Ohio, have invented certain new and useful Improvements in Metal Shingles, of which the following is a specification.

The present invention has for its Object to provide an improved form of metallic shingle, such as are commonly used for roofing pur oses.

T e invention is more particularly directed to that type in which the metal shingles are joined together by means of an interlocking relation of their side edges.

A further object of the present invention consists in providing metal shingles with side locking means, which not only form an absolutely weather proof junction against the action of rain and snow, but will permit the desired amount of ventilation.

Shingles embodying the features herein set forth possess further advantages in that the side lock isformed entirely above the surface of the shingles, thus absolutely safeguardingthe entrance of any water or moisture, since by this arrangement there is no trough or low place in which either might collect.

l/Vith these and other objects in View, the invention consists in the construction and arrangement of parts as 'more fully described and set forth in the following specication and appended claim.

In order that a clear understanding of the invention may be obtained, reference is made to the accompanying drawing in which similar parts are indicated by reference letters of like character, in the different views, and in which- Figure 1 is an enlarged sectional view of the locking means, taken on line 1--1 of Fig. 2; Figs. 1a and 11b are views illustratin the manner in which the parts are a plie to each other before assuming the ocked position of Fig. 1; Fig.'2 is an elevation illustrating several shingles assembled', as upon a roof, showing an application of the invention; Fig. 2 is a sectional detail taken on the line 2-2, Fig. 2.

Referring to the drawings by reference characters, A represents the metal shingles which are substantially rectangular in form. One of the lateral edges of each shingle (the left hand edge in the illustrations) is creased so as to form a groove or channel l, having anopening in its under side into which a corresponding portion of the adjoining shini gle is adapted to register. In detail this channel is formed by bending the metal upwardly at right angles to the surface of the shingle, shown at 2, from thence the metal extends horizontally, parallel to the surface of the shingle as shown at 4, forming the upper wall of the groove 1. The metal is then bent downwardly, at right angles to form the side wall 5, parallel to 2, but `of greater length than 2. The edge of the sheet is bent at 6, forming the lip '7 which is inclined upwardly and inwardly and against which the tongue of the adjacent shingle contacts at the point 8.

The o posite lateral edge of each shingle (the rig t hand edge in the illustrations) is made with an up-raised li or tongue, formed by creasing the meta and bendin it to assume the Shape shown at 9. Beyon the tongue 9 the metal is stamped to form the lateral corrugation 10 of substantially Semi-circular cross-section, upon which the adjoining shingle rests. The edge of the metal then extends in a horizontal direction in the same plane as the surface of the shingle, and terminates at a suitable distance beyond the junction in the mail flange 11 which is fastened to the boards of the roof by tacks or nails 12. i i

In order to join the successive shingles forming' one tier or row across the roof, the shingle at the extreme left is first nailed in lace. The manner in which the succeeding shingles are applied and locked together will be clearly understood by referring to Figs. 1 and 1b. In the former it will be seen the shingle to be applied is held in a position at right angles to the one already 95 1n place having the wall 5 of the groove 1 resting flat on the surface of the fixed shingle. By turning the shingle downwardly about the elbow G as an axis, the tongue 9 enters the groove 1b), and the locked position of Fig. 1 results. It is now im ossible to remove the top shingle from tie lower one, even though it is 'moved slightly to the left.

The rib 9 within the groove 1 contacts 105 at 8 with the up-turncd lip 7, but docs not touch the wall 2 of the groove, thus allowing a slight adjustment in each shingle. Each shingle, after being locked in the proper position, is nailed down at its fur- 110 1 (as shown in Fig. 100

ther edge and successive ones applied in similar manner. N

lach of the shingles is provided near its upper end with a series of three or four horizontal ribs 13Iof Senn-circular,"form.

These serve to prevent" the. entrance of rain or iiioistuije that* might be beaten upward. 'rhc nailing liaiige 1l is adapted to overlap the ribs 13, and is provided with a depression llithrough which the nail is driven (see Fig. 2a). l

rEhe lower Vedge of each shingle is pro. vided with a depending flange 16 having an arch-shaped notch 17 at its middle point. llfhen the shingles are placed upon a roof they are arranged in horizontal tiers one above another, as illustrated in Fig. 2. The depending iiange 16 fits snugly over the lowermost rridge 13 of the corresponding shingle in the lower tier and the notch 17 `bridges the wall of the groove l, as shown.

Careful exalnination'of this form of side lock will show that there are no raw edges of metal exposed. Furthermore there are no places where flat surfaces of the metal contact, thus obviating any danger of leaks through capillary action. The points of contact are three in number, and can bedesignated by the point 8, the place whereA the elbow 6 touches the surface of the shinglie and the top of the ridge l0.

yan angle of approximately 45 substantially as described. y

:imaaea y Having described myinvention l claim-:e- A metallic shingle having a joint lock member at one edge thereof, consisting of a raised tongue or lip formed by creasing the` f metal and bending the same at an angle 1 .upwardly and rearwardly, a second ridge nearer the edge of the shingle'of substantially seiiiicireular cross section, and a nail,n ing flange extending in the same plane aS thel surface of the shingle, the other edge of said shingle being formed with an overlap` ping member formed above the, surface of the shingle, said overlapping member comprising a lateral strip of metal, extending u ward from the surface of the shingleiat right angles, thence horizontally in plane parallel with the surface of t e shingle, thence vertically downward toa point contacting with the surface ofthe adjoining shingle.,

at a point contacting with the. surface of the raised tongue of the adjoining surface,
